Equil. Constants and Temperature

Postby Marie_Bae_3M » Mon Nov 14, 2016 4:49 pm

So, if K changes with temperature, then how is that shown with the equilibrium constant expression? Is it based on the P=MRT equation and the molar concentration changes, so the equil. constant also changes, or is there another equation that relates equil. constants and temperature?

When temperature of the system increases, a reaction requiring heat energy (endothermic reaction) can now make more of that product (I am going to say product because the reaction goes both ways and in a sense, both sides are endothermic then). Therefore, the concentrations will go up because more mols can be dissolved in reactants and products, and the K constant will change depending on if the reactants or product side has more mols.
